Hi NicoD,
Thanks for your insights.
I am fairly new in Linux as in using it, but have read a lot. So I did know the Ubuntu comes from Debian for instance. Although now administered separately.
Your note above does helps me, so many thanks. I believe a mention of just using what you want should be mentioned in the beginners guide. I didn't see anything like it. Also, which distribution name belongs to what vendor. But that's just my opinion.
CasaOS seems interesting but more than what I need at this stage.
Building my own is again more that what I am prepared to do stuff this stage, too daunting.
